(Cl. .Z4- 150) 3 Claims.

This invention relates to pin elements, such as the catch or the pin stem joint, which consist of a base member of Celluloid or other plastic material and a metallic member xedly attached to said base member. The metallic member serves as a hook if the pin element is a catch and as a bearing member for the pin stem if the pin element is a pin stem joint. This invention has as its general object the production of a pin element having a new and improved structure for attaching the metallic member to the base member.

In the pin elements of the Celluloid base type now in general use, the metallic member is attached to the Celluloid base member by means of prongs which are formed on the metallic member and which are driven into the base member. These prongs are objectionable because they are sometimes bent in the act of driving with the result that they do not firmly attach the metallic member to the base member. These prongs are also objectionable because they are on the same line or extend parallel to the pin stem joint. As a result, the pin stem, when under stresses resulting in the course of wear, acts as a lever which tends to dislodge the metallic member from the base member. It is an object of this invention to produce a pin element which will be free of the foregoing objectionable features.

For the purpose of describing my' invention with the particularity required by law, I have shown in the drawings which form a part hereof, and I will now describe, a catch and a pin stem joint wherein the metallic member is attached to the base member by means of my novel structure.

Figure 24 is a top View of the member shown in Figure 22.

Referring more particularly to the drawings, wherein similar reference numerals denote similar parts, reference numeral l designates the the base. A portion of the base has been broken catch shown in Figures 9 toll. The catch l consists of the base member 2 and the hook member 3.

The base member 2 (see Figures 5 to 11) is made of Celluloid or other plastic material and has formed therein the slot 4 which receives the foot 1 of the catch 3.

The catch 3 is formed from the blank 5 shown in Figure 1 and consists of the hook portion 6, the foot 1 and the anchoring ngers 8. The hook portion 6 is deemed to be the body element.

The catch 3 (see Figures 1 to l1) is made by first bending the arm 9 of the blank 5 in the manner necessary to cause it to form the hook portion 6 shown in Figures 3 to 11. The foot 1 of the blank 5 is then inserted into the slot 4 of the base member 2 and caused to assume the position shown in Figures 6 to 8. (In this position, the lower face II of each of the shoulders II) formed in the hook member 3 contacts the upper face I2 of the base member 2, and the anchoring ngers 8 extend beyond the lower face I3 of the base member 2.) Then the anchoring fingers B are bent outwardly and caused to assume the position shown in Figures 9 to 11. The hook member 3 is now firmly anchored to the base member 2 and the base member 2 is iirmly clamped between the shoulders I3 of the hook member 3 and the anchoring fingers 8 of said hook member.

Referring more particularly to the structure shown in Figures 12 to 24, referencenumeral I4 designates the pin stem joint shown in Figures 22 to 24 inclusive. The pin stem'joint I4 consists of the base member I5 and the bearing member I3 in which the pin stem I1 is rotatably mounted.

' The base I5 (see Figures 18 to 24) differs from the base 2 only in the fact that the slot I8 is made big enough to snugly receive the feet 24-24 ofthe bearing member I6.

The bearing member I6 (see Figures 14 to 24) is made from the blank I9 shown in Figures 12 and 13 by rst bending the same into the form shown in Figures 14 to 21. (When this is done, the element 2) of the blank IS becomes the wall 2B of the bearing member, the bridge 2I of the blank IQ becomes the bridge 2i of the bearing member, the wall 22 of the blank I9 becomes the wall 22 of the bearing member, the arm 23 ofthe blank I9 becomes the wall 23 of the bearing member, the feet 24H-24 of the blank I9 become the feet 24-'24 of the bearing member, and the fingers 23-25 of the blank I9 become the fingers 25p-25 of the bearingl member. The walls and 2 2, the bridge 2l, and the wall 23 are deemed to be the body portion of the bearing member I3.) The feet 21B-240i therbearing member I6 are now positioned within the slot I8 of the base member I5 and caused to assume the position shown in Figures V19 to 2,1. (Inthis position, the lower face 26 of the bridge 2| and the lower faces 21 and 28 of the wall 20, and the wall 23 contact the upper face 29 of the base member I5. and serve as shoulders for said bearing member.) IThe lingers -25 are now bent to the position shown in Figures 22 to 24 where they Y said walls inwardly at a point over the bight of the eye. The crimping produces the protuberances 32-32 which enter the bight of the eye 3| and serve both as pivots for the pin stem and as the means for attaching the pin stem I1 to the bearing member I6.

It is clear from the foregoing disclosure that the novel pin element, whether a catch or a pin stem joint, consists of a base member of Celluloid or other plastic material and a metallic member which is xedly attached to said base member. The metallic member consists of a body portion which is fashioned to function as a hook in the event that the pin element is a catch, and as a bearing member for the pin stem in the event that the pin element is a pin stem joint. In each case, the body portion of the metallic element terminates at the lower edge thereof in a pair of spacedfapart shoulders from which extend a foot or feet which in turn terminate in anchoring ngers. The lower face of each of the shoulders contacts the upper face of the base member. The foot or feet extend into the slot formed in the base member` The combined length of the foot or feet and their respective locking fingers are such that the lower face of the foot will not extend beyond the lower face of the base member, and the locking fingers may be turned to be flush with the lower facev of said base. When finished, the shoulders, the feet, and the locking ngers serve as the means for rmly clamping the base member to the body portion of the metallic member. It is to be noted that each finger is bent at right angles to the long axis of the slot. As a result, these ngers are always at right angles to the axis of the pin stem, This plus the shoulder and foot structure counteracts the force exerted by the pin stem which tends to pull the metallic member out of the base member.

Having described my invention, what I claim as new Yand useful is:

1. A pin element consistingv of a at base member of plastiomaterial and a metallic member iixedly attached to said base member; said metallic member consisting of a body portion having spaced apart shoulders formed therein at the lower edge thereof with the lower faceY of each of said shoulders contacting the upper face of said base member, a foot extending from said body portion at a point between said shoulders and into said slot, and anchoring fingers extending from said foot, eachrof said anchoring fingers bent atV right angles to the long. axis of said slot to be iush withthev lower face of said base member, said shoulders, foot, and fingers combining to clamp said base member to said body portion.
